Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56
0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11
Therefore, the speed of the current is 3 miles per hour. Answer is 3 miles per hour
Kx+9=7
Kx=-2 (subtract 9 from both sides)
X=-2/k (divide k from both sides.
10$ because i worked it out and valedictorian in my math class so listen to me yeah
6. Classify the angle as acute, right, obtuse, or straight.
A. obtuse
B. acute
C. straight
D. right
(THE ANSWER IS OBTUSE ANGLE)
An Obtuse Angle Is what your looking at right now. Its angle is bigger than 90 degree.
A Acute angle is lower than 90 degree which tends to make something looking like the “<” “>” sign.
And straight angle is just a straight line (No kidding)
A right angle is justs a L shape sign. The corner of the L 90 degree
